performance
statistics
- are measurements of the total input and output operations
(I/O), memory, and CPU time used to process individual DATA or PROC steps.
You can obtain these statistics by using SAS system options that can help
you measure your job's initial performance and to determine how to improve
performance.

system
performance
- is measured by the overall amount of I/O, memory, and CPU
time that your system uses to process SAS programs. By using the techniques
discussed in the following sections, you can reduce or reallocate your usage
of these three critical resources to improve system performance. While you
may not be able to take advantage of every technique for every situation,
you can choose the ones that are best suited for a particular situtation.
